Part L SFP

I am dealing with the entry of Specific Fan Powers for the Part L compliance.

Previously I have been advised when using Hevacomp I should calculate the average SFP for the fan as Hevacomp doesn't take into account the switching off of the fan using occupancy sensing.

If it is entered using the full SFP Hevacomp calculates the energy use for the it running the whole occupied time.

Please could you advise if this is still the case.
